Whoopie Slings
Haven Whoopie Slings are hands-down our favorite hammock camping accessory.
Weighing in at only 2 oz / 57 g, these slings extend up to 12 ft / 365 cm and give you full control over your campsite selection so you can hang your hammock exactly where you want without hunting for the perfect tree spacing.
The Whoopie Sling's adjustable loops work like a finger trap to hold their place under tension, making them easy to dial in to your desired length. Despite their ultra lightweight design, these slings are made from 3.5 mm UHMWPE with a breaking strength of 1800 lbs (850 kg), so they can handle real-world use in all conditions.
Even if weight is not your main concern, Whoopie Slings are the ideal hammock camping companion because they give you flexibility in where and how you hang.
Spectre Straps option
On this page you can also choose Spectre Straps - our ultralight hammock suspension system that combines tree straps and Whoopie Slings into one tidy setup. Spectre Straps are designed around Haven Spectre but are compatible with all Haven Tent models as well as most gathered end and bridge style hammocks.
Trail weight: 3 oz | 85 g
Each set includes:
• 2 x lightweight 1 inch tree webbing (50 in | 1.27 m)
• 2 x adjustable UHMWPE Whoopie Sling (96 in | 2.44 m)
Bonus:
• 2 x daisy chain extensions with 10 segments (39 in | 1 m) - perfect for oversized trees or tricky site geometry.
Together, each strap spans 150 in | 3.8 m, giving you a combined span of 25 ft | 7.6 m.
The Whoopie Sling portion locks under tension but adjusts easily when slack, making your setup quicker and your site selection more flexible than ever. Whether you are shaving ounces or just want a clean, fast suspension, Spectre Straps are built for versatility, comfort, and speed.
